Need a recommendation please

I'm looking for a fish that would be good at eating algae but will be ok in a nem tank. Or should I just stick with snails and a urchin?

I always liked emerald crabs for algae sometimes a pita though. What size tank is it for?

I’m in the same boat limits our choices no tangs unfortunately. There are a few algae eating gobies and blennnies and some angel fish are good algae eaters but they might nip at corals.

To name a few:
Cherub angel
Potters angel
Lemon peel angel
Lawnmower blenny
Red lipped blenny
Mimic blenny
Rainfords goby
Brown barred goby
